HEBEI YUETONG FASTENERS MANUFACTURING CO.,LTD’s screw products—including stainless steel screws, lead screw, and m3 screws—embody precision, durability, and versatility. Backed by advanced manufacturing, global certifications, and rigorous quality checks, these screw variants meet the diverse needs of industries worldwide. Whether for woodworking, automation, or electronics, their commitment to excellence ensures reliable performance in every application.

Cargol: Core Characteristics and Production Excellence

Cargol is a fundamental fastener designed to create secure, removable connections by threading into materials or mating with nuts, and HEBEI YUETONG’s products exemplify quality. Crafted from high-quality carbon steel—chosen for its tensile strength and machinability—their screw variants, such as the Hex Wood Screw with Zinc White (DIN 571), are built to withstand torque and resist stripping during installation. Many screw products undergo zinc plating, a surface treatment that enhances corrosion resistance, making them suitable for indoor and mild outdoor applications, such as furniture assembly or woodworking.

Adhering to international standards like DIN 571, the screw dimensions (thread pitch, length, head size) are precision-engineered to ensure compatibility with materials and tools. For example, their hex wood screws feature sharp, self-tapping threads that grip wood securely, while the hexagonal head allows easy tightening with wrenches. Advanced production equipment—including precision threading machines—guarantees consistent thread quality, ensuring smooth insertion and reliable holding power. Strict quality checks, from raw material inspection to final testing, ensure every screw meets rigorous standards, making them ideal for both industrial and consumer applications.

Stainless Steel Screws: Corrosion Resistance for Harsh Environments

Stainless Steel Screws are a specialized variant of screw designed to resist rust and corrosion, making them indispensable in harsh environments. HEBEI YUETONG produces stainless steel screws using high-grade stainless steel alloys (e.g., 304 or 316), which contain chromium and nickel to form a protective oxide layer, preventing moisture and chemicals from damaging the metal. This makes them ideal for outdoor applications (e.g., outdoor furniture, marine equipment), humid environments (e.g., bathrooms, kitchens), and industrial settings with chemical exposure.

Like their carbon steel counterparts, stainless steel screws adhere to international standards (DIN, ANSI), ensuring compatibility with standard tools and materials. They are available in various head types (hexagonal, flat, pan) and sizes, including m3 screws, to suit diverse needs. The company’s advanced manufacturing processes—including precision machining and heat treatment—ensure stainless steel screws maintain their strength and corrosion resistance over time, even under heavy loads. This reliability has made them a preferred choice for customers in regions like South America and the Middle East, where exposure to harsh climates is common.

Lead Screw: Precision Motion in Mechanical Systems

Lead Screw is a specialized screw designed to translate rotational motion into precise linear motion, a critical function in machinery and automation. HEBEI YUETONG produces lead screw using high-strength alloy steel, chosen for its durability and ability to maintain precision under repeated use. The lead screw features a long, threaded shaft that mates with a nut; as the shaft rotates, the nut moves along its length, driving linear motion in components like sliding tables, lifts, or conveyor systems.

Engineered to tight tolerances, lead screw products from HEBEI YUETONG offer low friction and high positional accuracy, making them suitable for applications in robotics, 3D printers, and industrial automation. They can be customized with different thread pitches (to control movement speed) and coatings (e.g., Teflon) to reduce wear. Compliance with industry standards ensures compatibility with motor systems and other mechanical components, while strict quality control—including testing for thread uniformity and load capacity—guarantees consistent performance in demanding environments.

M3 Screws: Compact Size for Fine Precision Applications

M3 Screws are small-diameter screw variants with a thread diameter of 3mm, designed for precision fastening in compact spaces. HEBEI YUETONG’s m3 screws—available in carbon steel and stainless steel—adhere to international standards, featuring precise thread pitches (typically 0.5mm for fine threads) and head sizes (e.g., hexagonal, Phillips) to suit specific tools.

These tiny but robust screws are widely used in:

• Electronics, securing circuit boards, connectors, and small components.
• Precision machinery, fastening delicate parts in medical devices or optical equipment.
• Miniature furniture and models, where small, unobtrusive fasteners are needed.
• Automotive electronics, such as sensors and control modules.

The company’s advanced manufacturing capabilities—including micro-machining—ensure m3 screws have consistent threading and dimensional accuracy, preventing stripping and ensuring secure fastening in delicate applications. Their corrosion-resistant variants (stainless steel) are also available, making them suitable for electronics used in humid environments.

Frequently Asked Questions (FAQs) About Screws and Variants

What materials are used in screw production by HEBEI YUETONG?

HEBEI YUETONG primarily uses high-quality carbon steel for standard screw products, with zinc plating for corrosion resistance. For specialized applications, they offer stainless steel screws (304/316) and lead screw made from alloy steel, ensuring strength and durability across diverse uses.

How do stainless steel screws differ from carbon steel screws?

Stainless steel screws contain chromium and nickel, forming a protective oxide layer that resists corrosion, making them ideal for outdoor or humid environments. Carbon steel screws, while strong, require zinc plating for basic corrosion resistance and are better suited for indoor, dry applications.

What is the key function of a lead screw in machinery?

A lead screw converts rotational motion (from a motor or handle) into precise linear motion, driving components like sliding tables or lifts. This makes it essential for automation, robotics, and machinery requiring accurate positional control.

In which applications are m3 screws most commonly used?

M3 screws are used in small-scale, precision applications such as electronics (securing circuit boards), miniature machinery, and delicate assemblies (e.g., medical devices, optical equipment) where compact, secure fastening is needed.

Does HEBEI YUETONG offer OEM services for screw variants?

Yes, the company provides OEM services for all screw variants, including stainless steel screws, lead screw, and m3 screws. Customers can customize size, material, coating, and head type to meet specific requirements, with all OEM products undergoing the same strict quality control as standard offerings.
